Okay, that makes sense! Events. Ah...

And it suddenly reminds me of where I've seen callbacks that didn't annoy me: signal handlers.

Would I be going out on a limb if I said the use of callbacks in Net::IMAP is a little .. er.. funny?

For those of you who haven't had the (dis)pleasure of working with that particular module, if you want to know the size of an email message, you send a query to the IMAP server and get the results via callback.
